Hotpoint Wd860 F-01 Fault - Help Needed

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Hotpoint WD860 showing F-01 and running drain pump

The problem

Hotpoint WD860 powers up and allows a programme to be selected, but as soon as the cycle starts the drain pump runs, the display flashes END then F-01, and the pump stays on. The machine could only be stopped by unplugging it.

Likely cause

The accepted reply states that on most Hotpoint machines an F1/F-01 fault commonly points to a faulty motor triac. The module and its connections were also advised to be checked. This is a likely diagnosis rather than a confirmed failed part.

What fixed it

Do not replace the PCB speculatively. Check the control module and its connections, as advised in the accepted reply. Because PCB fault diagnosis can be expensive and easy to misdiagnose, further diagnosis should be carried out by a suitably qualified appliance engineer.

Checks to try

• Observed that the pump starts immediately when the programme begins
• Observed END flashing followed by F-01
• Check the control module and its connections
